IMPROVEMENT in THRAsHlNe-MACHINl-:sl

The Sehedule'rvef'e'edto in these Letters Patent and making parl: of thesame.

Z'o all whom item1/y concern,

Beit known that I, HlRAM E. HUnLBUnLof Hammondsport, in theicounty ofSteuben and State of New York, have invented a new and valuableImprovenient in Thraslling-lvIachines; and I do hereby declare that thefollowing is a full, clear, and exact description .of the constructionand operation of the same, reference being had to the annexed drawingmaking a part of this specification, and tothe letters and iignres ofreference marked thereon.

` Figure 1 of the drawing vis a side view of my invention. l

Figure 2-is a plan view ot the same..

My invention relates to means fr thrashing grain; and consists in anovel arrangement and combination of devices intended to serve as anefficient apparatus in the department ofagrieultnre referred to.

A of the drawing l'epresents the two sides-of a frame, of which B is thebedieee.

'At each end of this frame I arrange'rollers, one of which is marked aand the othere on the drawing, each of which is arranged for revolvingin suitable bearings in the side-pieces A.

C represents a revolving'shaft arranged upon' proper bearings in vorunder the vside pieces A, having a cord voir belt-pulley, d, at itsright-hand end, and a crank'- wheel, g, atnits left-hand end.

D is an endless belt, which moves around the roll- Aers a and e, Aasshown.

G isa crank-wheel affixed to the` end of roller a, and is constructedwith a groove on its lperiphery to liold'a belt or cord. p

A cord or belt, h, works in the groove above mentioned, and actuates theshaft G in the manner show-n on fig. 2.

H is a ratchet-wheel attached to the left-hand end of roller a, for thepurpose hereinafter mentioned.

K is an oscillating bar, arranged in bearings on the tops of theelevated parts of side-pieces A, as shown, and is actuated in the mannerhereinafter described.

The letters lv are beaters, constructed ot' bent iron rods, of the formshown on Iig'. 1, and connected with the bar K, in the mannerrepresented.

The letter n is a pitman extending from the pin or Y.

crank on wheel g to the lever s, to which it is pirot-ed.

P represents a dog or pawl pivoted to the lever s, and operating withtheV teeth of the ratchet-wheel H, as represented. By means of this dogand ratchetwheel the endless belt is prevented from moving back-v ward,except at-the will. of the operator. When vde sirable, however, the dogis raised from 'the ratchet and the said belt may be made to reverse itsmovements.

To operate my thrashing-machine, the power is applied to wheel G, whichsets'the endless belt and `beaters in motion. rIhe grain, in the straw,is then placed on the right-hand end of the belt, and is earried underthe beaters, when it is thrashed by the blows thereof. n It will bereadily perceived that, after thrashing by my process, the straw remainsunbroken, which'resuit isimpossibleto obtain by the use of athrashingcylinder. l

I claim as my inventionl l. rlhe thrashing-machine herein described,consisting of the frame A B, the shaftiG, endless belt D, f crank-wheelsG and g, .bar K, rollers a and e, pulley d, pitman'a, lever s, andbeaters V, constructed and arranged toA operate substantially as setforth.- 2. In combination with the above-described thrashing-machine,the ratchet-wheel H and pawl P, when. arranged to operate as and for thepurpose-specified. l

'In testimony that lI claim the above I have hereunto subscribed my nameinthe presence of two wit- HIRAM E. HURLBURT. Witnesses:
